OK, so:

Power = Work Done / Time taken

Hopefully you found out Work Done from earlier part....

Now, speed = distance * time ==> time = speed / distance...

We appreciate your wanting to help, but please note the guidelines for replying to questions

http://www.thestudentroom.co.uk/wiki/Study_Help_Guidelines#answering_questions

It asks that you do not post complete solutions to calculations.
The idea is to help the poster answer it for himself, and not to do the question for him.

Thanks for your cooperation in this.
